Journal of engineering physics Aims and scope

Abstract

An analytic method is proposed for solving nonstationary heat conduction with transport coefficients dependent on the coordinates. The temperature distributions in soils have been examined for harmonic and exponential laws of variation for the air temperature in greenhouses.
